This striking vintage war poster features the Union Jack alongside a bold patriotic call: “It’s Our Flag — Fight for it, Work for it.” Originally published in 1915 by the Parliamentary Recruiting Committee, it was designed to rally support for Britain’s war effort during the First World War.

The poster’s powerful message appealed to both soldiers and civilians, urging all citizens to contribute — whether on the battlefield or the home front. The Union Jack, rendered in vivid red, white, and blue against a dark green backdrop, symbolises national unity and pride. Its dramatic folds and central placement reinforce the emotional weight of the appeal.

Created during a time when Britain relied heavily on voluntary enlistment, this poster was part of a broader campaign to stir patriotic duty and collective action. It would have been displayed in public spaces across the UK, from railway stations to town halls, reminding passersby of their role in defending the nation.

This high-quality reproduction preserves the original’s bold typography and rich colours, printed on premium paper using archival inks for lasting impact. It’s a powerful piece of wartime history — ideal for collectors, educators, or anyone with an interest in British heritage and propaganda art.
